Hiya andto the forums, enza. I'm sure you'll find this a much more welcoming and friendly atmosphere to learn and share. There's a lot of information and knowledge on this site, maybe browsing through the forums will get your imagination going.
Have you talked about this openly with your guy? Explored what it is that makes him hot, what he wants to happen? And how about you...imagining that he's all yours, to do with as you please...what comes to mind?
You don't have to answer those questions here, it's just something to think about, to get your fantasy going. The only advice I'd give is to talk, talk, talk to him, explore each others fantasies. I'm pretty sure the rest will come naturally...
*grins* maybe reading a little in the Library will give you a few ideas as well.
Have fun and enjoy the forums,
Silke
